The RQ/SRQ of HIP08 needs one special sge to stop receive reliably. So the
driver needs to allocate at least one SGE when creating RQ/SRQ and ensure
that at least one SGE is filled with the special value during post_recv.

Besides, the kernel driver should only do this for kernel ULP. For
userspace ULP, the userspace driver will allocate the reserved SGE in
buffer, and the kernel driver just needs to pin the corresponding size of
memory based on the userspace driver's requirements.

rxe_udp_encap_recv() drops the reference to rxe->ib_dev taken by
rxe_get_dev_from_net() which should be held until each received skb is
freed. This patch moves the calls to ib_device_put() to each place a
received skb is freed. It also takes references to the ib_device for each
cloned skb created to process received multicast packets.

rxe_net.c sends packets at the IP layer with skb->data pointing at the IP
header but receives packets from a UDP tunnel with skb->data pointing at
the UDP header.  On the loopback path this was not correctly accounted
for.  This patch corrects for this by using sbk_pull() to strip the IP
header from the skb on received packets.

rxe_rcv_mcast_pkt() in rxe_recv.c can leak SKBs in error path code. The
loop over the QPs attached to a multicast group creates new cloned SKBs
for all but the last QP in the list and passes the SKB and its clones to
rxe_rcv_pkt() for further processing. Any QPs that do not pass some checks
are skipped.  If the last QP in the list fails the tests the SKB is
leaked.  This patch checks if the SKB for the last QP was used and if not
frees it. Also removes a redundant loop invariant assignment.

Instead of open coding the loop for port iteration, use rdma_for_each_port
macro provided by core.

To use such macro, early initialization of phys_port_cnt is needed.
Hence, initialize such constant early enough in the init stage.

Whichever functions are called with port using rdma_for_each_port(),
convert their port type from u8 to unsigned int to match the core API.

Currently mlx5 driver caches port GID table length for 2 ports.  It is
also cached by IB core as port immutable data.

When mlx5 representor ports are present, which are usually more than 2,
invalid access to port_caps array can happen while validating the GID
table length which is only for 2 ports.

To avoid this, take help of the IB cores port immutable data by exposing
an API to read the port immutable fields.

Remove mlx5 driver's internal cache, thereby reduce code and data.

Pkey table length for all the ports of the device is the same.  Currently
get_ports_cap() reads and stores it for each port by querying the device
which reads more than just pkey table length.

For representor device ports which can be in range of hundreds, it queries
is for each such port and end up returning same value for all the ports.

When in representor mode, modify QP accesses pkey port caps for a port
index that can be outside of the port_caps table.

Hence, simplify the logic to query the max pkey table length only once
during device initialization sequence.
